APPLICATIONS
The Am186CC/CH/CU microcontrollers, with their integrated communications features,
provide highly integrated, cost-effective solutions for a wide range of telecommunications
and networking applications.
■
ISDN Modems and Terminal Adapters: Next-generation ISDN equipment requires
USB (or High-speed UART capability), in addition to three channels of HDLC.
■
Low-End Routers: ISDN to Ethernet-based personal routers, often used for
connections in Small Office/Home Office (SOHO) environments, require three channels
of HDLC, as well as the high performance of a 16-bit controller.
■
Linecard Applications: Typically, linecards used in Central Offices (COs), PABX
equipment, and other telephony applications require one or two channels of HDLC.
Linecard manufacturers are moving to more lines per card for analog POTS as a means
of cost reduction. This, and digital linecards for support of ISDN, often requires higher
performance than existing 8-bit devices can offer. The Am186CC and Am186CH
microcontrollers are ideal solutions for these applications because they integrate much
of the necessary glue logic while providing higher performance.
■
xDSL Applications: Today’s xDSL applications, such as high-speed ADSL modems,
require data handling of 2 Mbit/s or greater and can take advantage of the USB interface
for easy connectivity to the PC.
■
Digital Corded Phones: Typical digital telephone applications use up to three channels
of HDLC and may use USB for merged PC telephony applications.
■
Industrial Control: Embedded x86 processors have long been used in the industrial
control market. These applications often require a robust, high-performance processor
solution with the capability to easily communicate with other parts of a system. The
Am186CC and Am186CH microcontrollers provide numerous interfaces to achieve this
communication, including the SSI interface, high-speed UART, and the HDLC channels,
which also can be used to create a multidrop backplane.
■
USB Peripheral Devices: These devices will become more common as the PC market
embraces the USB protocol specified by the Microsoft™ Windows 98 operating system.
In addition to implementing communications device class systems such as an ISDN
terminal adapter, the USB peripheral controller makes the Am186CC and Am186CU
USB microcontrollers suitable for certain PC desktop applications such as a USB camera
interface, ink-jet printers, and scanners.
■
General Communications Applications: The Am186CC/CH/CU microcontrollers will
also find a home in general embedded applications, because many devices will
incorporate communications capability in the future. These microcontrollers are
especially attractive for 186 designs adding HDLC, USB, or both.
The block diagrams beginning on page 1-5 show some typical designs. Figure 1-4 shows
an ISDN terminal adapter. Figure 1-5 shows a low-end router. Figure 1-6 shows a 32-
channel linecard.
The ISDN terminal adapter features an S/T or U interface and either a high-speed UART
or USB connection for attaching the modem to the PC.
The ISDN-to-Ethernet low-end router features an S/T or U interface, two POTS lines, and
a 10-Mbit/s connection to the PC.
The 32-channel linecard design demonstrates a linecard application where 32 lines
terminate on the linecard.
